>banks, stocks, personal data, etc would be vulnerable

Well no, because most banks are already well on the road to post-quantum. Most major browsers support hybrid PQC handshakes. Some larger banks have enabled this on their public-facing web servers. The backend cryptographic elements for most major banks are already PQC, and no major bank is going to non-PQC keys for any new internal project in 2026.

As for personal info, Signal has migrated already (they started some years ago, being smart). Google drive is already protected by hybrid PCQ and well on the way to full.

Just because the Bitcoin is by and large in denial, doesn't mean everyone else is.

So then it seems pretty straight forward for Bitcoin devs to follow the trend and upgrade to match the broader industry.

Don’t freeze any keys, just allow people to use quantum resistant addresses

You'd think so!

The reality is that Bitcoin hasn't even chosen a key type yet, let alone put the wheels in motion for a protocol-wide transition. Everything is stuck in philosophical debates about if to upgrade at all, and if yes then how. And that's for bitcoiners talking about it at all, most are stuck on jpegs in the op return.

Citibank, HSBC and the like are about 7 years ahead of Bitcoin at this point.
